The official Pottermore Insider has finally announced the release date for all users to Pottermore, along with an update on the beta progress.

April 2012. That’s the date! The blog goes onto to say that there have been some fairly large-scale changes behind the scenes to do with the architecture that Pottermore runs on ensuring the new facilities better support all the millions of people anxious to give the system a try.

We gathered some incredibly useful feedback from our Beta users, and it became clear that our original platform wouldn’t be suitable when millions more users came on to the site. So we made a big decision: to move Pottermore to an entirely different platform set up. This ‘invisible’ change has involved a lot of work behind the scenes but it will enable our users to get the best from Pottermore as it grows and develops.

There have definitely been some challenges and the whole Pottermore team has been working really hard to incorporate all the Beta activity and feedback. This means that over the coming weeks and months we’ll be adding exclusive content and many more exciting features (such as sounds) to Pottermore for you to explore, share and discover.

What do you think this “exclusive” content will mean? Will J.K. Rowling have contributed even more?
